1. Investigation of Fracture in an Interface Crack Between Bone Cement and Stainless Steel
AbstractInterface strength is considered as one of the most influential factors in the long-term durability of the replaced joint in cemented total hip replacement. Several researchers have suggested that the damage initiation in a replaced joint is a mechanical phenomenon primarily taking place in the vicinity of cement-prosthesis interface. In this study,

2. Desenvolvimento de uma nova prótese para substituição de disco da coluna vertebral lombossacra através da metalurgia do pó
O presente trabalho desenvolveu uma nova prótese para substituição de disco da coluna vertebral lombossacra, dividido em três macros etapas. Primeira etapa: conceito biomecânico e projeto assistido por computador (CAD/CAE), simulando estruturalmente o modelo virtual do implante. Segunda etapa: análise dos processos de fabricação, metalurgia do pó co

3. Fibrinolytic therapy for thrombosis in cardiac valvular prosthesis short and long term results
OBJECTIVE: To assess the short- and long-term results of the use of streptokinase (SK) for the treatment of thromboses in cardiac valvular prostheses. METHODS: Seventeen patients with cardiac prosthetic thrombosis diagnosed by clinical, echocardiographic, and radioscopic findings underwent fibrinolytic treatment with a streptokinase bolus of 250,000 U follow

4. Viability of pHEMA Hydrogels as Coating in Human Synovial Joint Prosthesis
In artificial joints, the bone part is usually substituted by a metallic component with high corrosion and strength resistance while the articular cartilage is replaced by a polymer. Use of thin layer of a compliant material acting as a bearing surface in human replacement joints has recently generated considerable interest. This work analyses the coating of

5. Metodologia para avaliação de fluxo sanguineo em cirurgias vasculares com Doppler de ondas continuas
At present, the main difficulty found in vascular surgery is the evaluation of intra-operatory haemodinamic performance of vascular prosthesis. The proposed system uses a continuous wave Doppler directional ultrasonic equipment, a microcomputer and a cardiac monitor . The ultrasonic transducer is fixed on arteries and/or prosthesis using a special device, de

6. A 29-Year-Old Harken Disk Mitral Valve: Long-Term Follow-up by Echocardiographic and Cineradiographic Imaging
An 81-year-old woman was evaluated for prosthetic mitral valve function. She had received a Harken disk mitral valve 29 years earlier due to severe mitral valve disease. This particular valve prosthesis is known for premature disk edge wear and erosion. The patient's 2-dimensional Doppler echocardiogram showed the distinctive appearance of a disk mitral valv

7. Efficacy of Teicoplanin and Autoradiographic Diffusion Pattern of [14C]Teicoplanin in Experimental Staphylococcus aureus Infection of Joint Prostheses
Prosthesis infections are difficult to cure. Infection with methicillin-resistant staphylococci is becoming more common in patients with orthopedic implants. Using a recently developed model of methicillin-resistant Staphylococcus aureus (MRSA) infection of a knee prosthesis, we compared the efficacies of teicoplanin and vancomycin.
